The McGregor Fund is a private foundation organized "to relieve the misfortunes and promote the well-being of mankind." It was established by a $5,000 deed of gift from Tracy W. McGregor in 1925, and later augmented to nearly $10 million through subsequent gifts from Mr. McGregor and his wife, Katherine Whitney McGregor. Through their generosity, over the past 82 years the Fund has provided nearly $180 million in assistance to organizations serving the metropolitan Detroit area.

Over the years, the Fund has continued to be faithful to the stated intent of the donors. Grants to relieve misfortune and promote well-being are made in the following program areas: human services, education, health care, arts and culture, and public benefit. The area of principal interest to the McGregors, metropolitan Detroit and the tri-county area, remains the primary focus of the Fund.
